DISPLAY-SIGN.

Application filed June 30, 1921.

To all whom it may concern Be it known that I, CARL FRED BOETTCHER, acitizen of the United States, and resident of Henry, in the county ofScotts Bluff and State of Nebraska, have invented certain new and usefulImprovements in Display- Signs, of which the following is aspecification.

This invention relates to display signs and more particularly to theilluminating means for the same.

An important object is to provide a display sign having novel meanswhereby the number of electric lights necessary to illuminate the signis reduced to a minimum.

A further object of the invention is to provide a display sign in whichthe electric lights are so located that the entire matter to bedisplayed is uniformly and brilliantly illuminated.

Further, the invention aims to provide a display sign which is neat inappearance, of highly simplified construction and cheap to manufacture.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawing forming a part of this application and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a perspective of the improved s1 '11.

Fig. 2 is a central vertical longitudinal sectional view through thesame,

Fig. 3 is a vertical transverse sectional view through the same.

In the drawing wherein for the purpose of illustration is shown apreferred embodiment of the invention the numeral 5 gener allydesignates the improved sign which is in the nature of a casing havingupper and lower walls 6 and 8 respectively between which end walls 10are arranged. The upper and lower walls 6 and 8 of the casing may bejoined by spaced bolts 11 extended through the end portions of the walls6 and 8 which as illustrated in Figs. 1 and 2 extend beyond the endwalls 10.

The spaced parallel sides 12 are formed of glass or other transparentmaterial and Specification of Letters Patent.

are received within longitudinally extending grooves 14 in the innersides of the walls 6 and 8 and are securely held in position by thefastening bolts 11. In carrying out the invention, the inner surface ofeach glass 12 may be formed with a coating of paint and may be providedon its outer side with suitable display matter. The coating of paint onthe inner side of each glass does not prevent the light from shiningthrough the glass but prevents the electric light bulbs 15 and thereflectors 16 from being seen from the outerside of the casing.

As illustrated in Fig. 2, one reflector 16 is arranged at each end ofthe casing and is secured thereto by a base plate 17. The electric lightbulb is in turn extended through the reflector 16 and is threaded into asocket 18 extended through the end wall and having connection with anelectric light wire 20.

The inner sides of the improved display sign may be provided with acoating of reflecting material so that the light rays from the bulbs 15arranged at the ends of the casing will be uniformly projected throughthe oppositely arranged transparent sides 12. By having the light bulbs15 at the ends of the casing the display signs 12 are brilliantly anduniformly illuminated, so that the display matter applied to the samemay be conveniently seen.

I claim A display sign comprising upper and lower walls having theirlongitudinal edge portions formed with longitudinal grooves opening outthrough the ends of the walls, a pair of spaced parallel glass sidessecured in said grooves and terminating short of the ends of said upperand lower walls, end walls arranged flatly in contact with the ends ofsaid glass sides and engaging said upper and lower walls, light bulbscarried by said end walls and having inwardly directed re flectorsdirecting the light rays toward each other whereby to uniformlyilluminate the glass sides, and pairs of bolts extending through theterminal portions of said upper and lower sides outwardly of said endwalls and detachably holding the end walls and said sides firmly inposition.

CARL FRED BOETTCHER.
